Is there an environment variable that I can append a path to in order to add another .h file to the ones already included in “/houdini/vex/include/”?

Specifically, I'm concerned with “voplib.h” and “voptype.h”, would it be possible to write extra functions into a header that can be called in the vex builder? Or should I be going the OTL route?

I may be wrong and miss your question, but if you want to add new VEX functions, you may have to use the HDK for that.

If you run

hconfig -ap |& less


You'll see a list of all the paths, including HOUDINI_VEX_PATH.

If you create $HOME/houdini8.0/vex/include, you can put headers in there which are picked up when compiling VEX. Or anywhere else in the houdini path.

Unfortunately, it doesn't appear that hconfig reports the paths scanned for includes.

[Edited for correction to $HOME path – thank you craig]

Is that $HOME/vex/include, or $HOME/houdini8.1/vex/include?
